To @ZZ vwhom it may concern:

Be it known that I citizen of the United States, residing` atThomasville, in the county of Thomas and State of Georgia, have inventedcertain new and useful improvements in Paclings for Automobile and otherAxles; and l do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, ret erence beingnhad to the accompanying drawings, and to the figures oit' referencemarked thereon, `which forni a part of this specification.

This invention relates to an improvement in packing, proposing aconstruction which is especially adapted for automobile axles and theirbearings', but which may also be adapted :lor analogous or kindredapplica tions to prevent the escape or loss'ot the oil or grease inwhich the bearings run and also to protect the hearings against dust.'-

The principal. objects of the invention are to provide a packing for thepurposes stated. which. shall be simply constructed', durable and Wearcompensating; which may be employed in connection. with any existingtype oft roller bearing, whose individual parte are readily accessibleand renewable as the occa sion may require; and which "nas markedefficiency for its contemplated purpose.

With the foregoing objects and advantages in View the invention consistsin eaturcs of construction and combination ot' the yielda'ble orcoinpressible packing rings and their associated par-ts as 'will morefully a pear from the succeeding; description.

A preferred embodiment oi' the invention is illustrated in theaccompanying drawing, wherein i Figure l is a longitudinal sectionalview showing the improved packing as applied to an automobile axle.

Fig. l is a sectional view on the line 2-2 of Fig. l.

Fig. 3 is a perspective view showing the construction of the springswhich act on the jyieldahle or conipressilole packing rings.

Similar characters of reference designate corresponding` partsthroughout the several views.

Fig. i of the drawing shows an automobile axle whose spindle 2 projectsinto a Whccl hub 3 and is `iournaled ina bearing of approvedconstruetiranj that shown compris- JERRY H. BRAKE, a-

Y

The spaces between the packing rings are sealed and the rings themselvesare protected access of dust and oil by flat washers 14 and l5 whichsurround the axle l and bridge the space between said axle and the innerface of the hubextension 9, the inner and outer edges ot said Washersbeing very close to the concentrioiaces of the axle and the hubextension. Since no metal is precii sented at the sides of the packingringe, thowashers i4- and l5 mayy be held in strong contact with saidrings, preferably exerting a measure of "lateral ,compression thereon.,In the embodiment disclosed the Washer la bears against the cone et andthe Washer if receives the thi-listet an adjusting nut or follower i6threaded Withinv the huh entension 9. Obviously, by` suitably tighteningthe nut or follower 1G aga-inst the washer l5, both Washers le and 15may be held 'with desired or necessary pressure against the opv againstaccess of dust; and the Washers tc-` gether with the strings if?. and 13canse the Sti peekingeiings m1 eiieieeiy prevent oil er grease iiomeeeepfng from-fthe bearing along ehe sui-feces @f izhe heb extension andthe axle. in iiis wey the pecking provides e. 5 substantially eiii'ghtend Weil' or closure for +die feaiirig housing without, however, in anying'. .3. y. i.
